Gps and total distance problem

4692300 over 2 years ago

Actual total distance is 205.6km.

But fr955 record only 200.99km and recorded route is some problem.

I already setup gps multibend and every second.

I attached image of log.

Going around 25km/hr over twisty paths is simply very tricky, even with 1sec recording. The difference is about 2%, that's not too crazy right? That's like 200m over a 10k route...

Also, did you…

The map when shown in Garmin Connect does not show "every second". Try viewing the FIT file in another tool (eg. Strava).

Also, did you have clear view or were there many trees/obstructions, cloudy/clear sky? Quite some things that can influence it, but this doesn't sound crazy at all (again, already because of speed + bendy path). 25km/hr is 7m/s...

Agreed. At running pace that would have been better traced, but at bike speeds the very tight radii of those curves would have been undersampled at 1 GPS point per second.
